Available in PDF, EPUB and Kindle. Book excerpt: " . . . . . . Nature has something more in view than that its own proper males should fecundate each blossom. " Andrew Knight Philosophical Transactions, 1799 Sterility implicating the male sex solely presents a paradoxical situation in which universality and uniqueness are harmoniously blended. It maintains a built-in outbreeding system but is not an isolating mechanism, as male steriles, the "self-emasculated" plants, outcross with their male fertile sibs normally. Both genes (nuclear and cytoplasmic) and environment, individually as well as conjointly, induce male sterility, the former being genetic and the latter nongenetic. Genetic male sterility is controlled either exclusively by nuclear genes (ms) or by the complementary action of nuclear (lr) and cytoplasmic (c) genes. The former is termed genic and the latter gene-cytoplasmic male sterility. Whereas genic male sterility exhibits Mendelian inheritance, gene-cytoplasmic male sterility is non-Mendelian, with specific transmissibility of the maternal cytoplasm type. Genetic male sterility is documented in 617 species and species crosses com prising 320 species, 162 genera and 43 families. Of these, genic male sterility occurs in 216 species and 17 species crosses and gene-cytoplasmic male sterility in 16 species and 271 species crosses. The Predominance of species exhibiting genic male sterility and of species crosses exhibiting gene-cytoplasmic male sterility is due to the fact that for the male sterility expression in the former, mutation of nuclear genes is required, but in the latter, mutations of both nuclear and cytoplasmic genes are necessary.
Download or read book Biology and Utilization of the Cucurbitaceae written by David M. Bates and published by Cornell University Press. This book was released on 2019-05-15 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cucurbits (Cucurbitaceae, or gourd family), which include squash, pumpkin, melon, cucumber, and watermelon, have long been of economic significance. As sources of vegetables, fruit, and seeds rich in oils and protein, they have the potential of making an even larger contribution toward meeting the needs of humankind. This book, consisting of 37 papers by 50 cucurbit specialists, emphasizes the practical importance of cucurbit investigation, and also provides a broad overview of the family.
Download or read book Handbook of Genetics written by Robert C. King and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this and future volumes of the Handbook of Genetics is to bring together a collection of relatively short, authoritative essays or annotated compilations of data on topics of~ignificance to geneticists. Many of the essays will deal with various aspects of the biology of certain species selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclopedic amount o( information available on such a species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is bewildering to a novice and sometimes even to a veteran geneticist working with evolu tionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive behavior, and cul ture methods for the species in question. What are its particular ad vantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibliographies, and how or mutant strains? A list giving the sym does one get stocks of wild type bolism for unknown mutations is helpful, but it need include only those mutants that have been retained and are thus available for future studies. Other data, such as up-to-date genetic and cytological maps, listings of break points for chromosomal aberrations, mitotic karyotypes, and hap loid DNA values, will be included when available.

Download or read book Genetics Genomics and Breeding of Cucurbits written by Yi-Hong Wang and published by CRC Press. This book was released on 2011-11-11 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two decades has been the most exciting period in cucurbit genetic, genomic, and breeding research especially for cucumber, melon, and watermelon. In addition, cucumber became the first cucurbit to be sequenced, after other field crops such as rice, sorghum, soybean, and maize. In thirteen chapters by 34 internationally renowned scientists, this book provides an in-depth review of the state of the art of genetic and genomic research conducted in cucurbits. It will be an essential resource for cucurbit researchers as well as scientists working in other crops.

Book excerpt: or fruit production as a consequence of the lack of optimum pollination conditions (CLARK and FRYER, 1920; ARMSTRONG and WHITE, 1935; VALLEAU, 1918; KVAALE, 1927; and many others). In order to mini mize the influence of poor pollen producers, systematic planning of a field planting or an orchard might be necessary. Above all, the im portant reason for its wide popularity is its potential use in the com mercial production of hybrid seed. A male-sterile plant is an effective female for a crossing program and its employment renders the labori ous procedure of emasculation superfluous. ]ONES and EMSWELLER (1937) and STEPHENS (1937) were probably the first to outline a scheme of its application in onion and sorghum respectively. However certain specific problems have limited the practicability and hence some of them will be mentioned in a later seetion (Section VIII). Lately several attempts have been made to obtain some chemie al method for the artificial induction of male sterility. However, for a successful approach to the induction problem a thorough understan ding of various pathways that bring about pollen abortion in naturally occurring cases, would be of great value. It may be hoped that data from these induction experiments alongwith the available biochemi cal analyses would lead to the emergence and elucidation of useful information of both theoretical and practical interest.
